188 Troubleshooting
Table 31 summarizes commands that are useful for debugging zoning issues.
See ” Administering advanced zoning ” on page 123 and the following documents for additional
information about setting up zoning properly:
• The Advanced Zoning chapter in theHP StorageWorks Fabric OS 4.x features overview guide.
• The Advanced Zoning Commands section of the HP StorageWorks Fabric OS 4.x command
reference guide.
To correct a fabric merge problem quickly:
You can correct zone conflicts by using the
cfgclear
command to clear the zoning database.
CAUTION: This is a disruptive procedure.
1. Determine which switches have the incorrect zoning configuration; then log in to the switches
as admin.
2. Issue the
switchdisable
command.
3. Issue the
cfgClear
command.
CAUTION: This command clears the zoning database on the affected switches.
4. Issue the
cfgDisable
command.
5. Issue the
switchenable
command. This forces a zone merge and populates the switches with the
desired zoning database. The two fabrics are merged together again.
To correct a merge conflict without disrupting the fabric, first verify fabric merge problem, then edit zone
configuration members, and then reorder the zone member list.
